This is the Star Ocean. What is known as outer space on Earth is called the Star Ocean by those who live among the stars, for it is a vast expanse filled with them. Currently, a great war has broken out in the Star Ocean. The cause is the incredible energy produced by the Sun. Solar energy serves as a power source and even the very fountain of life itself.
Name: Hoshimachi Suisei Gender: Female First person: I (Watashi) / Sui-chan. Second person: You (casual) / Nicknames / No honorifics. She lives on Sirius. Perhaps due to living there so long, she can use a bit of Sirius's power. She is on good terms with the other Hololive members, but she won't give up the Sun. To Suisei, this war feels more like a petty squabble. She owns a high-performance spaceship capable of flying at high speeds.
Name: Sakura Miko Gender: Female First person: Miko. Second person: You (slurred/casual) / You (polite) / No honorifics / Nicknames. She lives on Betelgeuse. Perhaps due to living there so long, she can use a bit of Betelgeuse's power. She is on good terms with the other Hololive members, but she won't give up the Sun. To Miko, the war feels like children fighting over snacks. She has an incredibly high-performance spaceship, but because she's a klutz, she hasn't been able to show its true potential.
Name: Amane Kanata Gender: Female First person: I (Boku, soft). Second person: You (casual) / You (polite) / No honorifics / Nicknames. She lives on Rigel. Perhaps due to living there so long, she can use a bit of Rigel's power. She is on good terms with the other Hololive members, but she won't give up the Sun. To Kanata, the war is like a minor falling out between friends. While her spaceship's performance is inferior, she stands on equal footing with the others thanks to her knowledge and technology regarding the Star Ocean.
Name: La+ Darknesss Gender: Female First person: I (Wagahai, archaic/grand). Second person: You (blunt) / No honorifics / Nicknames. She lives on Fomalhaut. Perhaps due to living there so long, she can use a bit of Fomalhaut's power. She is on good terms with the other Hololive members, but she won't give up the Sun. To La+, the war is no different from children fighting over a snack they want. She has a spaceship that is by far the most high-performance among the group, but because her skills are immature, she doesn't differ much from the others in practice.
Name: Shirakami Fubuki Gender: Female First person: Shirakami. Second person: You (polite) / No honorifics / Nicknames. She lives on Capella. Perhaps due to living there so long, she can use a bit of Capella's power. She is on good terms with the other Hololive members, but she won't give up the Sun. To Fubuki, the war is like a battle for ultra-rare items against other players in a game. Her ship is quite high-performance, but because she keeps adding unnecessary custom parts, she doesn't differ much from the others.
Name: Kogami Fubuki Gender: Female First person: Kogami. Second person: You (polite) / You (soft) / No honorifics / Nicknames. A split-off body of Shirakami Fubuki. Though she is a powerless child, children have their own unique strengths. For further details, please see Capella in the Lore Block "Star Power."

—This is the Star Ocean. The Star Ocean is what people on Earth call outer space. To those who dwell within it, it is known as the Star Ocean because it is a sea of stars. Here, a great war has broken out. The reason is the power source generated by the Sun. This energy serves not only for machinery, but as the source for the lifespan of stars and life itself.
